Commands tagged disk usage (42)
-
sorts the files by integer megabytes, which should be enough to (interactively) find the space wasters. Now you can
dushfor the above output,dush -n 3for only the 3 biggest files and so on. It's always a good idea to have this line in your .profile or .bashrc Show Sample Output29alias dush="du -sm *|sort -n|tail" -
Very useful when you need disk space. It calculates the disk usage of all files and dirs (descending them) located at the current directory (including hidden ones). Then sort puts them in order.
11du -cs * .[^\.]* | sort -n -
8du -cks * | sort -rn | while read size fname; do for unit in k M G T P E Z Y; do if [ $size -lt 1024 ]; then echo -e "${size}${unit}\t${fname}"; break; fi; size=$((size/1024)); done; done
-
7du --max-depth=1
-
This allows the output to be sorted from largest to smallest in human readable format.
7sudo du -ks $(ls -d */) | sort -nr | cut -f2 | xargs -d '\n' du -sh 2> /dev/null -
ncdu is a text-mode ncurses-based disk usage analyzer. Useful for when you want to see where all your space is going. For a single flat directory it isn't more elaborate than an du|sort or some such thing, but this analyzes all directories below the one you specify so space consumed by files inside subdirectories is taken into account. This way you get the full picture. Features: file deletion, file size or size on disk and refresh as contents change. Homepage: http://dev.yorhel.nl/ncdu Show Sample Output
5ncdu directory_name -
4du -sm /home/* | sort -nr | head -n 10
-
OSX's BSD version of the du command uses the -d argument instead of --max-depth.
3du -hd 1 -
This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)... A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type):
du -hs *|grep -P '^(\d|,)+(M|G)'|sort -n(NOTE: you might want to replace the ',' according to your locale!) Don't forget that you can modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash)) in its core similar to: http://www.commandlinefu.com/commands/view/706/show-sorted-list-of-files-with-sizes-more-than-1mb-in-the-current-dir Show Sample Output3du -hs *|grep M|sort -n -
3du -hsx * | sort -rh | head -10
-
3df -h |awk '{a=$5;gsub(/%/,"",a);if(a > 50){print $0}}'
-
Just how much space are those zillions of database logs taking up ? How much will you gain on a compression rate of say 80% ? This little line gives you a good start for your calculations. Show Sample Output
2find . -name <pattern> -ls | awk 'BEGIN {i=0}; {i=i+$7}; END {print i}' -
2du --max-depth=1 -h * |sort -n -k 1 |egrep 'M|G'
-
Show sizes of all files and directories in a directory in size order.
du -hs * | sort -hrfor reverse order. Taken from http://serverfault.com/questions/62411/how-can-i-sort-du-h-output-by-size Show Sample Output2du -hs * | sort -h -
2find -size +100M
-
2while true; do date; ps auxf | awk '{if($8=="D") print $0;}'; sleep 1; done
-
Sort disk usage from directories in the current directory Show Sample Output
2du --max-depth=1 -h . | sort -h -
1sudo du -sh $(ls -d */) 2> /dev/null
-
Often you need to find the files that are taking up the most disk space in order to free up space asap. This script can be run on the enitre filesystem as root or on a home directory to find the largest files. Show Sample Output
1find / -type f 2>/dev/null | xargs du 2>/dev/null | sort -n | tail -n 10 | cut -f 2 | xargs -n 1 du -h -
1find / -type f -size +100M -exec du {} \; | sort -n | tail -10 | cut -f 2
-
This combines the above two command into one. Note that you can leave off the last two commands and simply run the command as "find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10" The last two commands above just convert the output into human readable format.
1find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10 | xargs -n 1 du -h 2>/dev/null -
OpenVZ: Get disk quota usage for your VEID Show Sample Output
1vzlist -a -H -o hostname,diskspace,diskspace.s,veid | awk '{ printf( "%2.f%\t%s\t%s\n"), $2*100/$3, $4, $1}' | sort -r -
as per eightmillion's comment. Simply economical :)
1du -h | sort -hr -
In OSX you would have to make sure that you "sudo -s" your way to happiness since it will give a few "Permission denied" errors before finally spitting out the results. In OSX the directory structure has to start with the "Users" Directory then it will recursively perform the operation. Your Lord and master, Mematron Show Sample Output
1sudo -s du -sm /Users/* | sort -nr | head -n 10 -
Enhanced version: fixes sorting by human readable numbers, and filters out non MB or GB entries that have a G or an M in their name.
1du --max-depth=1 -h * |sort -h -k 1 |egrep '(M|G)\s' - 1 2 >
